gnat_math_extensions's Issues

Incomplete constraint checks

Some of the constraint checks which check that matrix and vector ranges match are incomplete.

This was found by compiling with GCC 12, and resulted in PR105303.

ERROR Float: Complex_Generalized_Eigenvalues : Eigensystem_Constraints
    ADA.ASSERTIONS.ASSERTION_ERROR
    Exception Message: failed precondition from s-gearop.ads:569 instantiated at ada_numerics-generic_arrays.adb:139 instantiated at tests-complex_generalized_eigenvalues.adb:53 instantiated at tests-complex_generalized_eig

Another error, which didn’t occur on aarch64-apple-darwin21, was

ERROR Long_Long_Float (NAG ZGGEV example): Complex_Generalized_Eigenvalues : Eigensystem_Results
    ADA.ASSERTIONS.ASSERTION_ERROR
    Exception Message: Loop_Invariant failed at s-gearop.adb:494 instantiated at ada_numerics-generic_arrays.adb:200 instantiated at tests-complex_generalized_eigenvalues.adb:53 instantiated at tests-complex_generalized_eig

but this was caused by a NaN causing a variable to not be ’Initialized.
